Answer:
6.43 moles of NF₃.
Explanation:
The balanced equation for the reaction is given below:
N₂ + 3F₂ —> 2NF₃
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Finally, we shall determine the number of mole of nitrogen trifluoride (NF₃) produced by the reaction of 9.65 moles of Fluorine gas (F₂). This can be obtained as follow:
From the balanced equation above,
3 moles of F₂ reacted to produce 2 moles of NF₃.
Therefore, 9.65 moles of F₂ will react to to produce = (9.65 × 2)/3 = 6.43 moles of NF₃.
Thus, 6.43 moles of NF₃ were obtained from the reaction.
Answer: 15.0
Explanation:
1) The chemical formula of silver nitrate is AgNO₃
2) The chemical formula of silver chloride is AgCl
3) Therefore, by mass balance you know that all the atoms of Ag in AgNO₃ will en up at the AgCl. This is a mole ratio 1:1.
4) Since, there are 15.0 moles of Ag atoms in 15.0 moles of AgNO₃, you conclude, using the 1: 1 ratio, that 15.0 moles of AgCl are produced.
b) the number of electrons in the outermost electron shell.
c) the attraction of an atom for the electrons in a covalent bond.
d) the repulsion of electrons in one atom for electrons in another atom.
Answer:
c) the attraction of an atom for the electrons in a covalent bond.
Explanation:
Electronegativity, symbol χ, is a chemical property describing an atom's ability of to attract a shared pair of electrons to itself. It is influenced by the atomic number of the atom and the distance between the valence electrons and the charged nucleus. As the electronegativity number of atoms increases, the more the atom attracts electrons towards itself.
Electronegativity is the attraction of an atom for electrons in a covalent bond. It determines how strongly an atom pulls shared electrons towards itself in a molecule.
option c is correct
Electronegativity is the attraction of an atom for the electrons in a covalent bond. It is a measure of how strongly an atom pulls shared electrons towards itself when it forms a covalent bond with another atom.
For example, in a molecule of HCl, chlorine is more electronegative than hydrogen, so the chlorine atom pulls the shared electron pair towards itself, resulting in a partial negative charge on the chlorine atom and a partial positive charge on the hydrogen atom.
Electronegativity increases as you move across a row or period in the periodic table from left to right and decreases as you move down a column or group.
